Application filed November 8, 1920. Serial No. 422,613.

To all whom it may concern:

Be it known that l, Josnrrr O. HUGHES, a citizen of the United States,residing at Murphysboro, in the county of Jackson and State of Illinois,have invented new and useful Improvements in Knives, of which thefollowing is a specification.

This invention relates to knives, wherein the blade is arranged to slidewithin the handle and to be wholly concealed when not in use, theinvention residing in the con struction, whereby the blade may be heldfixed relatively to the handle in any desired position.

The nature and advantages of the invention will be better understoodwhen the following detail description is taken in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

blade 11. The handle is formed from a single piece of material, theopposite longitudinal edges of which are folded inwardly above the bodyportion of the handle, the;

edges 12 being spaced apart for the major portion of their length toprovide a slot 13. The folding of the edges 12 provides channels inwhich the blade 11 is arranged to slide, the blade being provided with aheaded I stud it by means of which the blade is manipulated} The handleis preferably of a len h slightly greater than the length of the b adeso that when the latter is retracted positioned within the handle itwill not pro ect therefrom to out the pocket in which the knife iscarried, or the fingers of the user. Projecting from one edge of theslot adjacent one end of the handle, is a lug 1-5 which bearsagainst theopposite edge of the slot, closing the slot adjacent one end of thehandle. This lug constitutes a stop for the stud 15, and consequentlylimits the adjustment of the blade when projected from the handle.

With a view of holding the blade in any deslred position along thelength of the handle, I provide the underside of the inturned edges witha plurality of vnotches 16. A leaf spring 18 is terminally secured tothe blade l7,the opposite extremity of the spring being curved in thedirection of the notches 16, the curved extremity 19 normally engage mgsaid notches to hold the blade against movement relative to the handle.When it IS desired to project the blade from the handle, the head of thestud is depressed thus moving the curved end of the spring out ofengagement with the notches. With the parts so arranged, the blade canbe readtill) Wit ily adjusted in either direction and subsequentadjustment the stem is removed from the headed stud whereby the springmoves its curved extremity into engagement with the proper notch to holdthe blade in its adjusted position.

A pin 20 extends transversely through the handle adjacent one endthereof, and is disposed with respect to the adjacent terminal of theknife blade to be engaged by the latter and limit the movement of theblade in one direction.

While it have shown the described what i consider the preferredembodiment of the invention, ll desire to have it understood that T donot limit myself to this exact construction, inasmuch as such changesmay be resorted to when desired as fall within the sec e of what isclaimed.

aving thus described my invention what if claim as new is v l. A knifecomprising a handle formed from a single sheet of material having itsfree. edges spaced to provide a longitudinal slot, a blade arranged forsliding movement within the handle, a stud projecting from the handlethrough a slot form'anipulating the blade, ahead carried by the stud,cooperating means carried by the blade and handle for holding the bladein different adjusted positions and a lug projecting from one of thesaid longitudinal edges of the handle to close one end of the slot tolimit illtl its longitudinal ed s spaced to define a slot, a knife bladesli able Within the handle, a stud carried by the blade and projectinthrough the slot, a head carried by the stu notches formed along one ofsaid longitudinal edges, a leaf spring supporting the stud on said bladeand having an ofi'set portion adapted to engage said notches for holdingthe blade in difierent adjusted positions,

meaaea means for limiting the movement of the 10 blade in one direction,and a lug projecting from one of said edges of the handle to close oneend of the slot and thereby limit the movement of the blade in theopposite direction.

In testimony whereof I aflix my signature.

JOSEPH O. HUGHES.
